To all whom t mary concern:

Be it known that I, SiLAs L. PARR, a

citizen `of the United States, residing at Oshkosh, in the county ofWinnebago and State of lViseonsin, have invented certa-in new and usefulImprovements in a Grate, of which the following is a specification.

This invention relates to new and useful improvements in grates forstoves or furnaces and has for its principal object to provide a gratestructure wherein means areV provided for pivoting the grate, meansbeing` further provided yfor oscillatingfthe grate.l

Another'. important objeetof the present invention is to provide a grateofthe above mentioned character, which is of such a construction as toenable the same to be'easily and efficiently operated whereby clinkers,

ashes, slate or stone may beremoved fromV -the fuel in the fire boxwithout interfering' with the burning of the fuel.

A further object of the invention is to provide a grate ofthe abovementioned character, which is simple in construction,

inexpensive, strong and durableand furthermore adapted for the purposesfor which-it is designated.

Other objects and advantages o f'this invention will become apparentduringA the course of the following description.

In the accompanying drawing forming` part of this specification and inwhichlike numerals designate like `parts throughout the same Flgure 1 1sa improved grate y associated therewith in sec tion and also showing theoperatlngmeans therefor, the 'section being taken substan-` tially onthe line1-1 ofFigure 2 and Figure2 is a top plan View ofFigure 1.

In the drawing wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates asupporting ring which is pivotally supported below the fire pot or box 2and directly above the ash pit 3 on the trunnions 4L which are arrangedat diametrically opposite points in the manner clearly illustrated inFigure 2 of the drawing.` The supporting ring is further provided withspider arms 5 and the purpose thereof will hereinafter be more fullydescribed.

Supported on the upper edge of the ring 1 is the grate 6 and the same isprovided on its under side with downwardly extending ears which arearranged at d'iametric'ally opposite points on the grate and extendad.-` jacent the outer edge of the iring. 1 in the manner clearlyillustrated inthe drawing. For the purpose of supporting the grate 6 inposition on the ring 1 rvI provide the diametrically extending bar 8lthe ends ofwhich extend through diametrically opposed openings providedin the depending ears 7 and any suitable fastening means lsuch as shownat 9 is adapted to extend through each end of the. bar 8 for preventingthe displace-1` drical socket 11 provided in the central portion 12 ofthe underside of the grate 6 in the manner clearly illustrated in`Figure 1. The purpose of this construction `will also be hereinaftermore fully described.

Secured tothe supporting ring 1 and depending therefrom is the rockerarm 13. The lower` end of the Yrocker arm is pivotally connected to theinner `end of the horizontally extending elongated linkv 14 showny at 15in the drawing. The outer end ofthe link liextends through theash pit 3and is pivotally connected to the lower endfof a 5` Y j Vpanoperatinglever 16in thejmanner shown vertical sectional view of the lower portionof a furnace showing my` at'17 This'construction provides a meansWhereby the supporting ring 1 and the grate 6, mountedthereon may-beptilted on the trunnions 1` so that a the grate is obtained.`

For the purpose of holding the supporting ring Vand grate at any desiredangle, I provide the toothed Vsegment 18avhich, is supportedV by thefurnace Aand to which is pivoted the lever 16 in the manner shown at 19.A pawl 20 associated with the lever 16 for engagement with the teeth onthe segment and an auxiliary handle such as is shown at 21 is providedfor the pawl `for releasing the same from engagement with the segmentalteeth in the manner well known in the art.

For the purpose of oscillating the grate 6, I provided the latter with adepending arm 22 which is arranged at a point adjacent the rocker arm 13and is preferably off center so as to enable the grate to Voscillate onthe pivotal movement` of supporting ring 1. The lower lend of the arm22is connected to the inner end of an elongated link 23 similar totlie'elongated link 14 and if desired, a ball and-socket joint such asis shown at 24 provides the connection between the inner end of theelongated.

link 23 and the arm QZ An operating lever 25 is pivotally connectedat'its lower end to the outer end of the link 23 and is furthermorepivotally supported on the seg'- mental bracket 18 on the lVhen it isdesired to oscillate the grate 6,

the lever 25 is actuated to cause a forward and rearward movementfof thearm22, the

grate resting on the upperV edge of the sup-A porting ring 1 and havingthe socket por, tion 11 receiving the central projection 6, the samewill act as a bearing whereby the grate mayoscillateon the ring'withoutinterfering with thesupporting ring or causing movement thereof.

ItV will thus be seen from the foregoing description, that a grate hasbeen provided wherein the same may be either tilted or oscillated forenabling clinkers, stones, slate or ashes to be removed from tlieburningfuel. in the Viie boxin -asimpleand efficient manner. The operatingmeans is further-r ment of my invention,"it is to lie-understoodthatvai'ious changes inthe size, ,sl1`ape `and arrangement of parts maybez'resorteddo without departing from thespirit of thein-4V vention andthe scope of the appended L claims;

VHaving thus described the invention, what'V I claim is 1. A gratestructure comprising av supporting' ring'pivotally supported in afurnace 'a fri-ate su orted on .the u l)er edge 3 D D of said ring,depending ears arranged .at diametrically opposite points on said grateand 'disposed adjacent the outeredge of the supporting ring, avloarextending through `opposite side of the lever 16. 1

openings provided in the ears, fastening means therefor, means fortilting said ring andthe grate supported thereon comprising a rocker armsecured at its upper end to the supporting ring, a horizontally disposedlink pivotally connected at its inner end to the lower end of the rockerarm, and means connected to the outer end of the link for actuating thesaine.

2. A grate structure comprising a supporting ring pivotally supported ina furnace, a' grate supported'on the upper edge of said ring, dependingears arranged at diametrically opposite points on said grate anddisposed adjacent the outer edge of the supporting ring, a bar extendingthrough openings provided in the ears, fastening means' therefor, meansfor tilting said iing and the grate supported thereon comprising arockerlarm secured at its upper end to the supporting ring, a horizontallydisposed link pivotally connected at its inner endv to the lower end ofthe rocker arm, means connected to the outer end of the link foractuatingthe saine, and means for oscillating the grate onsaidsupporting ring.

3. A gratel structure comprising a supporting ring pivotally supportedin a furnace, aI grate supported on the upper edge of said ring,depending ears' arranged at diainetrically oppositepoints on said grateand disposed adjacent lthe outer edgeof the supporting ring, a barextending through openings provided in the ears, fastening meanstherefor, means for tilting said ring and the grate supported thereoncomprising a' rocker; arin secured at its upper end tothe supportingring,'a`horizontal ly disposed link pivotally connected at yits innerend to the lower `endo-fy the rocker arm, lmeans connfect'edto the outerend of thelink for actuating the saine, 'means for oscillating the'grate` on said supporting ring, said last mentioned means comprising anarm depending from the grate ata point adjacent' the center thereof, aIhorizontally disposed link con-r nected at'its inner end to the lowerend of said arm, and ineans'connect'ed to the outer end of -said linkfor'actuating the same.

In testimony whereof I aiiix my signature.
